I am having total 6 computers, running a cyber cafe. Where as one is my domain machine, which I running in windows 7 OS, where other rest 5 computers are running in windows vista. All of them are connected in to the same network. I monitor rest group machine from my remote machine. But there is a problem that I am facing in my domain machine after upgrade domain system from windows XP to windows 7. Other group machines are not showing in the my network places, though I properly installed wireless driver. Any information regarding this issue, nay input will be appreciated greatly.
